Patent JP-H11304607-A (JP)
Title: Torque sensor
Inventor: CHIKARAISHI KAZUO
IPC: B62D119/00
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To reduce manufacturing cost without causing a trouble, e.g. significant deterioration of performance. SOLUTION: Rotary shafts, i.e., input and output shafts 1, 2, arranged coaxially and rotatably are coupled through a torsion bar 3. The input and output shafts 1, 2 are made of a general structural steel, e.g. S25C or S35C, which is a conductive magnetic body and coated with a thin film of Ni-P alloy by electroless nickel plating. A torque acting on the input and output shafts 1, 2 is detected as a variation of electromotive force being induced in coils 10, 11 through relative rotation involving torsion of the torsion bar 3.

Title: Tapping device
Inventor: ITOU ETSUROU
IPC: B23G1/18
Filed: 1982-07-12
Abstract: PURPOSE:To make either feed for a drilling part and a tapping part alterable, by forming a feed screw in a hydraulic piston shaft, thereby turning the feed screw to a screw shaft, while using the hydraulic feed in combination with the screw feed, in case of a feed drive of a tapping device for a combined pipe tap and drill. CONSTITUTION:When a hydraulic cylinder device 21 operates and a casing 2 moves forward at a rapid traverse as well as when the tip of a combined pipe tap drill 7 comes close to a work 35, a carrier 23 pushes a flow regulating valve 24 into motion, switching it to drilling feed. When drilling is over, a carrier 25 also pushes a limit switch 26 into operation, stopping a piston of the hydraulic cylinder device 21. Therefore, a solenoid clutch 20 is excited whereby the turning force of a spindle 4 is transmitted to an internal thread body 15 via gears 19 and 18. When the internal thread body 15 rotates, the thread body 15 travels on a feed screw shaft 13 in its axial direction, and consequently a combined pipe tap and drill moves forward together with the casing 2 as far as the amount of travel commensurate to the pitch.

Filed: 1988-05-20
Abstract: PURPOSE:To prevent the wrong alarms and the omission of alarms for improvement of the reliability of an alarm device by preparing plural sensors and setting the alarm conditions in response to the detecting signals received from said sensors for transmission of alarms. CONSTITUTION:A system includes plural sensors like a burglar sensor 7, a fire sensor 9, etc., and a disaster prevention controller SSS2 and a crime prevention controller FSS3 are set between a central controller MS1 and both sensors 7 and 9 respectively. When the sensor 9 detects a fire, an automatic fire alarm board 8 produces alarms immediately via a transmission line 10. While a crime prevention controller 5 receives a detecting signal and controls the alarm in case the sensor 7 detects an intruder. The controller 5 produces the alarms when a detecting signal is received within a fixed time or plural detecting signals form a prescribed pattern within a fixed time. In such a case, a preliminary alarm is produced in response to the first detecting signal. Thus the alarm conditions can be selected in accordance with the detecting subject or the working condition of each sensor. As a result, the wrong alarms and the omission of alarms are avoided and the reliability of an alarm device is improved.

Abstract: PURPOSE:To improve the production efficiency of reformed gas using an apparatus having simple structure by connecting a reaction tube to a raw material gas channel formed at the outer side of the reaction tube interposing a heat-radiation member therebetween and reforming the raw material gas with a catalyst filled in the reaction tube. CONSTITUTION:A raw material gas is supplied from the top of a vertical channel 25 for raw material gas when the temperature of the catalyst layer 23 in a reaction tube 22 reaches about 400 deg.C. The raw material gas is transferred downward in the vertical channel 25 as shown by the arrow, sent to the bottom channel 29 for raw material gas, divided to individual reaction tubes 22 and sent upward through the layer of the catalyst 23 in each reaction tube 22. At the start of feeding, the raw material gas is heated mainly with the heat of combustion gas supplied to the inner side wall of the reaction tube and then heated by the gradually increasing heat radiation radiating from a heat-radiation cylindrical member 30 to the outer side surface of the reaction tube 22. The heated raw material gas is subjected to chemical reaction under the action of the catalyst 23 to form a reformed gas, which is delivered from the top of the reaction tube 22. The temperature distribution of the catalyst layer 23 on the cross-section of the reaction tube 22 becomes uniform when the heat radiation from the heat-radiation cylindrical member 30 is sufficiently increased and, accordingly, the production efficiency of the reformed gas can be improved.

Title: Automatic hop-up type opening/closing gate door
Inventor: IKEMIZU MAKOTO
IPC: E06B11/02
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a hop-up type opening/closing gate door which is operated automatically, can manage with a small number of component parts, and whose space for accommodating a motor, etc., remains small. SOLUTION: A motor 8 is installed in a column 10, and a normal/reverse rotation changeover mechanism for reciprocating motions having a reciprocator 83 to make reciprocation with the regular and reverse operation of the motor 8 is installed between the motor 8 and the base end of the first arm. When the motor 8 is operated in the regular and reverse directions, the reciprocator 83 makes reciprocation, and a door is rotated for opening and shutting with the normal and reverse rotations of the first arm. This allows managing with a smaller accommodating space for the drive mechanism including motor than a conventional automatic hop-up type gate door in which a long stretching elevating/sinking member is elevated and sunk.  Because the drive mechanism consists of the motor 8 and the normal/reverse rotation changeover mechanism having reciprocator 83, this can manage with a smaller number of component parts in use than the conventional gate door arrangement.
